The G1-125 is Zontes' neo-retro scrambler for A1 and car-licence riders, and it arrived with a specification that embarrassed most of its class: a liquid-cooled DOHC four-valve single making around 14.6 hp, Bosch ABS as standard, a slipper clutch, and engine crash bars fitted at the factory. The detail that defines it, though, is the fuel tank - 20 litres on a 125. That is touring-bike capacity on a learner machine, and it is why owners use the G1 for weekend routes and forest tracks rather than just the commute.
What a 20-litre 125 actually gets bought
Because the G1 is used for distance, the accessory pattern skews towards touring rather than city styling. Luggage comes first: tail racks, soft roll bags and saddlebags, since a full tank means genuinely long days out. Wind protection is second - the scrambler stance and flat bar leave the rider exposed above about 90 km/h, so flyscreens and small sport screens are consistent sellers. After that the list is scrambler-specific: wide serrated footpegs for standing on gravel, hand guards, bar risers and grips. Note that Zontes already fits engine guards, so buyers here are usually looking for the parts the factory bars don't cover - radiator mesh, headlight grille and a sump plate.
Fitment
This collection covers the ZT125-G1, the "G1-125" naming used in Spain and Italy, and the G1-125 X trim. The G1 shares its platform closely with the 125U1 trail - Spanish press described the two as near-twins - so many engine-side and control parts interchange between them: levers, mirrors, filters, sprockets and chain kits. Bodywork, tank-mounted and rack-mounted parts do not. Check the variant on each product page before ordering.
